Luca is a ruthless and merciless gangster. Luca usually hides behind a masquerade of amiability and citing friendship as one of the most important values. However, he uses the term friendship to disguise his will to be obeyed and paid for what he sees as his due payments for operating on his territory. Luca is particularly callous and violent, threatening Giorno Giovanna for money, and refusing to listen when Giorno adamantly claims to have none.
